AutomationDirect’s SOLO is a single loop dual output temperature controller that can control both heating and
cooling simultaneously. There are four types of control modes: PID, ON/OFF, Manual, and Ramp / Soak control.
D
epending upon the particular model of controller, the available outputs include relay, voltage pulse, current, and
l
inear voltage. There are up to three alarm outputs available to allow seventeen alarm types in the initial setting
mode. SOLO can accept various types of thermocouple, RTD, or analog inputs, and has a built in RS-485
interface using Modbus slave (ASCII or RTU) communication protocol.

Box Contents and Unpacking Instructions
• Unpack the SOLO temperature controller from its shipping carton. Included in the carton is the temperature
controller, mounting brackets plus hardware and this Quick Start Guide.
• Inspect all equipment for completeness. If anything is missing or damaged, immediately call the
AutomationDirect returns department @ 1-800-633-0405.
• Inspect the part number to ensure the model received matches the output type required.
WARNING! Electric shock danger
1. To prevent electric shock, do not touch the AC terminals while the power is supplied to the controller.
This controller is an open-type temperature controller. Make sure to evaluate any dangerous application in
which a serious human injury or serious property damage may occur.
1. Always use recommended solder-less terminals: Fork terminal with insolation (M3 screw, width is 7.0mm, hole
diameter 3.2mm). Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Recommended tightening torque: 0.4 Nm
(4kgfcm). Applicable wire: Solid/twisted wire of 2 mm, 12AWG to 24AWG. Choose AutomationDirect part numbers
BM-00120, BM-00220 or BM-00320 depending on wire size. Be sure to tighten them properly.
2. Protect the controller from dust or foreign objects to prevent controller malfunction.
3. Do not modify or disassemble the controller.
4. Do not connect anything to the “Not used” terminals.
5. Make sure all wires are connected correctly.
6. Do not install and/or use the controller in places subject to: (a) Dust or corrosive gases and liquid. (b) High humidity
(c) Vibration and shock. (d) EMI / RFI (e) high temperature.
7. Turn power off when wiring or changing a temperature sensor.
8. Be sure to use wires that match the thermocouple types when extending or connecting the thermocouple wires.
9. Use wires with correct resistance when extending or connecting a platinum resistance thermometer (RTD).
10. Keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and
route power wires as far as possible from load wires to prevent interference and induced noise.
11. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity,
dripping water, corrosive materials, airborne dust and electric shock or vibration.
12. Make sure power cables and signals from instruments are all installed properly before energizing the controller,
otherwise serious damage may occur.
13. To prevent electric shock, do not touch the terminals in the controller or try to repair the controller when power is
applied.
14. Use a soft, dry cloth to clean the controller. Do not use acid or alkaline liquids for cleaning.
15. This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required, install
the protection close to the instrument. Recommended fuse rating: Rated voltage 250 V, Rated current 1 A. Fuse
type: Time-lag fuse
16. Note: This controller does not provide overcurrent protection. Use of this product requires that suitable overcur-
rent protection device(s) must be added to ensure compliance with all relevant electrical standards and codes.
(Rated 250 V, 15 Amps max). A suitable disconnecting device should be provided near the controller in the end-
use installation.
